摘要
为精细化确定轨道交通市郊线路快车停站方案,提出一套以市郊线路客流OD为核心导向的快车停站优化方案.首先,构建轨道交通区间选择费用函数,根据路径选择费用分配OD客流;其次,在客流分配的基础上,以乘客出行时间最短与企业运营成本最低为目标函数,以断面满载率、车站客流需求、优化时段发车次数约束等多重客观因素为模型约束,建立快车停站方案优化模型;最后,以S市地铁市郊线路 16号线基础数据为实例验证,运用带精英策略的非支配排序的遗传算法和GA混合(GA-NSGA-II)对停站方案优化模型求解.优化结果表明,在高峰时段乘客人均出行时间节省1.074 min,每个运营日车底运用数减少6列.
Abstract
In order to further determine the metro express stopping station,an optimization model of express stopping scheme based on origin-destination(OD)pair of passenger flow was established.Firstly,a road cost function was constructed to allocate OD passenger flow according to route cost.Secondly,taking the shortest travel time of passengers and the lowest operating cost of enterprises as the optimization objective,and taking multiple objective factors such as the cross section full rate,the station passenger flow demand,the number of times of the optimization period constraints as the model constraints,an express stop optimization model was builted according to passenger flow allocation.Finally,based on the basic data of metro line 16 in S city,the genetic algorithm with elite strategy and non dominated sorting,as well as GA hybrid(GA-NSGA-II)were used to solve the optimization model of stopping plan.The optimization results show that in peak hours,the per capita travel time of passengers is saved by 1.074 min,and the number of vehicles under each operation day is reduced by 6 columns.
